A frequency doubling crystal reset module

Abstract

The invention belongs to the laser technical field and relates to a frequency multiplication crystal reset module. The frequency multiplication crystal reset module is composed of a common bottom plate, a crystal assembly bottom plate, a plurality of ball head adjustment screw pairs, a crystal assembly, a plurality of magnet pairs and a plurality of ball head adjustment screw supporting seats; the crystal assembly bottom plate is arranged on the common bottom plate; the crystal bottom plate assembly is used for mounting a second harmonic generation module, a third harmonic generation module or a quadruplicated frequency module; the ball head adjusting screw pairs are used for adjusting the pitching angle or the center height of a frequency multiplication assembly; the magnet pairs are used for providing an absorption force for fixedly mounting the crystal assembly bottom plate; and the ball head adjustment screw supporting seats are used for the adjustment of the ball head adjustment screw pairs. With the frequency multiplication crystal reset module of the invention adopted, the influence of various kinds of adverse factors on the repeated mounting and positioning of a frequency multiplication crystal module can be decreased, and problems in quick replacement and precise positioning of frequency multiplication crystals can be solved.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a frequency doubling crystal reset module. Background technique [0002] The frequency doubling module is an important component of solid-state lasers and a necessary module for frequency doubling output. Lasers equipped with frequency doubling crystals are widely used in various fields such as scientific research, teaching, processing, and medical treatment. In the fields of scientific research and teaching, it is necessary to change the mode output frequently, from the base frequency to the double frequency, then to the triple frequency or quadruple frequency and even the mixed frequency output, which requires frequent and rapid replacement of the frequency multiplier module, and resets each time the frequency multiplier module is replaced If the accuracy is not enough, it will take a lot of time and effort to debug. [0003] There are many ways to install and use the frequency...

AI Technical Summary

Problems solved by technology

The reset accuracy of fixed installation and overall replacement of the frequency doubling crystal module is affected by many factors, especially the personal experience of different operators; the reset accuracy of the electric drive frequency doubling crystal module of guide rail installation is greatly affected by the accuracy of the limit switch, and the repeat positioning accuracy is low

[0004] The existing frequency-doubling crystal module is installed on the laser housing, and the housing is greatly deformed by the temperature. The deformation of the frequency-doubling crystal module is inconsistent with the deformation of the housing, resulting in a significant drop in crystal working efficiency.
